自卸式散货船自卸臂的风载荷数值模拟研究

Study on wind load numerical modeling of self-unloading arm of self-unloading bulk cargo ship

以自卸式散货船的84m自卸臂为研究对象,采用虚拟粘度方法,对两种典型工作状态下的模型进行了风载荷数值模拟。并将数值模拟结果与规范计算数据进行了对比,结果表明:基于Fluent的雷诺应力模型在数值模拟中预测结果相对较好。

With the 84m self-unloading arm of the self-unloading bulk carrier as a study object, the virtual viscosity method is adopted for wind load numerical simulation under two typical working states. By comparing the numerical simula- tion result and the standard calculation data, the result shows that Fluent-based Reynolds stress model can get a relatively better expected result in the numerical simulation.
